What do you have set as your "download folder" in Firefox? i.e., the Save files to setting in about:preferences under Downloads

I have set under Tools/Options/General tab "Ask me where to save files" Despite this, .rar objects are still downloaded to appdata folder. I have tried resetting about:config and all the download parameters nothing works Under the applications list (on the Tools/Options) I cant add .rar into the list of applications thus I cant "force" firefox to download objects of this type into the folder or force it to pop up and ask where I wanted my downloads to be stored.

I didnt set a "permanent" download folder in the General tab as sometimes I wanted my download on desktop and sometimes into my preference folder eg music/video/games etc depending on what I have downloaded
